libmtp error: Error getting friendlyname.

davidak commented 5 years ago

Issue description

I tried to copy files from my Android smartphone to my notebook using Pantheon Files.

For some files (all videos) i get this error:

libmtp error: Error getting friendlyname.

It is reproducible with this files.

syslog:

I noticed that the files seem to be broken. The video player on the smartphone stops playing in the middle...

@worldofpeace any idea?

That is the files which are videos that you tried to copy, correct? If so that sounds like a pretty dangerous issue.

yes

If so that sounds like a pretty dangerous issue.

why dangerous? i think since they are broken, it's not a big deal that i can't copy them. but i think it should be possible in general to copy even broken files

Oh now I understand. I was under the assumption that because you tried to copy them and it failed that it resulted in some sort of corruption. Can confirm that video files of the same file format that aren't corrupted can by copied?

Also, to find out if it's actually an issue in libmtp or really with like Pantheon Files and gvfs can you try to do the same operation but only with libmtp cli?

I think the https://wiki.archlinux.org/index.php/Media_Transfer_Protocol section `libmtp` should be helpful

yes. i copied some hundred files and only 5 or so had this problem

i already have deleted all files from my smartphone. so, no

Here are suggestions that might help resolve this more quickly:

Search for maintainers and people that previously touched the related code and @ mention them in a comment.
Ask on the NixOS Discourse.

Still important to me. Seen with a .jpg file in a similar file transfer situation.

NixOS / nixpkgs
